Be it known that l, BENJAMIN F.- Snr- MoUn, a citizen of the UnitedStates, residing at lllasliington, District lofaColumbia, have invented,certain new and useful lmprovements in Combined` TransmissionsandBearings, of whichthefollowing is a specification.

The present invention relates to resilient transmissions and bearings,more particularly for vehicle wheels,y and consists 1in the combinationsand arrangements of elements hereinafter described and particularly setforth in the accompanying claims.

The purpose of the invention is to provide a flexible or resilienttransmission between a driving andl a driven element adapted topositively transmit the driving force whether said elements are in orout of vconcentric relation, and oiiewhichwillv readily accommodateitself under all normal working` con ditions to which saidelements maybe subjected.

provide a combined resilient transmission and bearingA fora vehiclewheel to the-end that such a wheel may possess the desired resilientqualities and also give the necessary transmission medium between thewheel proper and themotive power of the vehicle. "llhc constructionshown herein is proposed asan improvement or other embodiment of thetypes of comb-ined resilient transmission and bearing disclosed in mycopending applications for United Statespaten-ts bearing the Serialllo,342,284 Dec. 3,1919, Serial No. 537,251 Feb 17, 1922, Serial No. 664:,-632 'iept.

`157,7,912 Dec. 18, 1923; 1,476,187,13'ec. 4, inea y Y L Theconstruction shown herein is characterized in` that the wheel. rim isnormally supported concentric on the wheel hub by a plurality ofeccentric cone and sleeve` elements and said eccentric elements: are coioperable to effect the `necessary resiliency to A further purpose of theinvention is to Y tration. in the accompanying `drawings wherein:

Figure 1 is. a .transverse sectional view p taken through. the wheel.

Fig. 2 is a face view of the wheel with the cover plate removed, andshowing the veccentric elements assembled,`

Fig 3, is. an enlarged transverse sectional View of a modifiedconstruction, and

Figure t shows in. fragmentary transverse Vsection a, modified form ofthe eccentric elements.

Referringto the parts in further detail, v

kand wherein. like reference characters designate corresponding members,the construe tion consists of a hub portion 3 havinga fixed anddisk-like side plate t located adjacent the vehicle body. (not shown);and 5` and 6 designate, respectively, theinner and p outer side platesofthe wheel rim Z which has limited movement relative to the wheel hub.The rim. plate 5 is disposed in bearing relation. aga-inst the hubplater 4: (see Fig. 1), anda number of angular bracing elements 8. arelocated between the rim Aplates 5 and 6 in the manner shown, Saidbracingl el'ements 8 may; be secured in `any suitable manner, e. g., bythe several bolts 9. v

The-resilient transmission and bearing device per se-consists ofanannular male cone element 10 yformed on the inner portion of the rimside plate 5, and said cone element 10 is eccentric with respect to ythewheel rim- A similar and eccentric female cone element 11 mounted on thewheel hub co-acts with said rim cone element 10` in va manner to beexplained, Said cone element 11 is adapted; to have lateral movementthrough the radial: inoveinentfimparted to the wheel rim astypical ofthe corresponding-Yelements disclosed in my pateuts and cio-pendingapplicationsabove 'referred to. Instead of the cone elementsl-O and 11there may be used complementary and intereiilgagingA grooved channeledelements 10a and 1.1a as-shown in Figure 4.

The inner portion l2 hof the, cone element 11 is. welded onor may beformed integral` with. an eccentric collar 13. The eccentric collar 13isili. turiimounted to slide-on a similar though wider eccentrickcollar* 14 whicliis rigidly mounted (e. g., shrunk) on the hub vportion3, to the. end thatthe. cone element 11 may have limited slidingmovement relative to the wheel hub incident to the limited radial orangular' movement imparted to the wheel rim.

The eccentric cone element 11 is held in close contact with theeccentric and rim cone 'element 10 by the spring 15 and through thetension of this spring said cone elements (l0 and 11) are held incooperative relation.

An adjustable collar 16, screw-threaded on the hub portion 3, serves forregulating the tension of said spring. And the 'removable rim plate 17readily permits of access for adjusting said collar and lubricating theworking parts, as will be understood.

In the construction shown in Fig. 3 the hub is provided with two sideplates 18 which sustain the two rim plates 19, said rim plates havingcone elements 20 eccentric with respect to the hub, and cooperable witha pair of similar cone elements 21 mounted on the wheel hub through theeccentric collars 22 and 23, as shown. A pair of springs 24 and 25normally maintain the eccentric cone elements in cooperative relation.The construction of this type of wheel is otherwise the same as thatshown in Figs. 1 and 2, and in like manner the principle of operation isthe same.

`It will therefore be seen from the foregoing that any motion or shockencountered by the wheel rim will be absorbed in the direction of theaxis of 'the wheel through the co-operable and eccentric cone elements,and this absorption of theV shock will be highly flexible or resilientin nature. Whenever forwarder reverse motion is imparted to the wheelhub the co-operable cone and eccentric elements will through frictionimpart turning to the wheel. rim with appreciably little or no lostmotion, and such transmission will be gradual and resilient.

Another and decided feature of merit of ythis construction is the savingof `the great kexpense heretofore required for ease-hardening the hub,grinding the same, and the avoidance of the necessity for keying thesleeve 14 on the hub.

It will'be clear from the foregoing that the construction disclosed andprinciple ofl nation of a hub portion, a wheel rim mount-` ed to havelimited relative movement thereon, and cone elements eccentricallyarranged co-operable therewith.'I
